It provides axial retention of shafts, pins, and other components without requiring a slot or hole in the retained part. The ring is manufactured from AISI 302 stainless steel, giving it strong corrosion resistance for wet, chemical, or washdown environments. It fits a 4.25-inch bore diameter with a free outside diameter of 4.52 inches, a groove width of 0.12 inches, a groove depth of 0.12 inches, and a ring thickness of 0.111 inches. Mechanical assemblers and maintenance technicians install this ring in industrial, hydraulic, and precision-machined assemblies.\u003c\/p\u003e\n\u003cp\u003eThis retaining ring is used in applications where a standard stamped ring cannot be installed from the end of a shaft or where continuous 360-degree contact with the groove is required. Spiral retaining rings are common in gearboxes, pumps, hydraulic cylinders, motors, and precision housings in industrial and commercial settings. The internal configuration means the ring seats into the bore groove to retain a component inside the housing. The 302 stainless steel construction makes it suitable for food-processing equipment, marine environments, and other corrosive-duty applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal spiral design provides full 360-degree groove contact for uniform axial load distribution\u003c\/li\u003e\n  \u003cli\u003eAISI 302 stainless steel construction meets AMS-5866 material specification for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eThrust load capacity rated at 36,050 pounds at groove safety factor and 59,280 pounds at ring safety factor\u003c\/li\u003e\n  \u003cli\u003eGroove width tolerance of 0.000 to 0.005 inches and groove diameter tolerance of -0.0060 to 0.0060 inches for precise fitment\u003c\/li\u003e\n  \u003cli\u003eNo slot or hole required in the retained component, preserving component strength\u003c\/li\u003e\n  \u003cli\u003eCompliant with ISO 13485:2016 and AISI 302 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machined housings with a 4.25-inch bore diameter groove, an inside diameter of 3.896 inches, a groove width of 0.12 inches, and a groove depth of 0.12 inches.

De-energize and lock out all power to the equipment before servicing any assembly containing retaining rings. Inspect the groove for burrs, corrosion, or out-of-tolerance dimensions before seating the ring. Do not over-compress or twist the ring during installation, as distortion will reduce load capacity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Outside Diameter\u003c\/strong\u003e: 4.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.896 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness\u003c\/strong\u003e: 0.111 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Thickness Tolerance\u003c\/strong\u003e: -0.003 to 0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width Tolerance\u003c\/strong\u003e: 0.000 to 0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Diameter Tolerance\u003c\/strong\u003e: -0.0060 to 0.0060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrust Load Capacity\u003c\/strong\u003e: 36,050 pounds (Groove Safety Factor); 59,280 pounds (Ring Safety Factor)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: AISI 302\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRing Type\u003c\/strong\u003e: Internal Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 302; AMS-5866; ISO 13485:2016\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.137 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROTOR CLIP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KG-425SJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROTOR CLIP","offers":[{"title":"Default Title","offer_id":51718365053234,"sku":"KG-425SJ","price":7886.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29a69c0aa71c152307354dd1c5168e00_28768d84-a680-4344-994b-32dd9a8ab8a8.jpg?v=1788552544","url":"https:\/\/voomisupply.com\/products\/rotor-clip-kg-425sj-internal-spiral-retaining-ring","provider":"Voomi Supply","version":"1.0","type":"link"}
